JOURNAL-BEARNG.

Specification of Letters Patent.

Patented J une 30, 1914.

Application filed 'May 29, 1913. Serial No. 770,699.

To all 'whom t may concern.'

Be it known that I, CLARANon H. CHARL- soN, a citizen of the UnitedStates, residing at Forest City, in the county of Winnebago and State ofIowa, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a specication, reference being hadto the accompanying drawings.

This invention relates to improvements in journals for cream separatorsor the like, and an object t-hereof is the provision of a journal inwhich friction is reduced to a minimum between the journal sleeve andthe rotatable shaft supported therein.

Another object of this invention is the provision of a bearing in whichthe wear on the rotatable shaft supported therein is compensated for.

Still another object of this invention is the provision of a bearingcomprising a sleeve having longitudinal slots therein, the slotscarrying springs which project within the bore of the sleeve, thesprings arranged on the sameside of the axial center of the shaft beingdisposed at right angles to each other.

With these and other objects in view, my invention consists in the novelconstruction, combination and arrangement of parts, to be hereinaftermore fully described, claimed and illustrated in the accompanyingdrawing, in which- Figure 1 is a vertical fragmentary section of' theneck of a cream separator or the like showing the journal connectedthereto; Fig. 2 is a top plan view of the journal; Fig. 3 is a verticalsection thereof; and Fig. lis a perspective view thereof.

Referring more particularly to the drawing, the numeral 5 designates aportion of the neck of a cream separator or other similar machine, theneck 5 having an inwardly extending flange 6 which is provided with acentral annular bore 7.

The numeral 8 designates a journal sleeve provided with a reducedextension 9, the eX- tension 9 of the sleeve being adapted forengagement in the bore 7 of the flange. The inner wall of the flange isprovided with a pair of diametrically opposite grooves 10, and securedto the lower edge of the extension 9 at diametrically opposite pointsare a pair of lugs l1 which project beyond the periphery of theextension for engagement in the grooves 10 when the extension is moveddownwardly within the bore 7 of the iange. The length of the extension 9is substantially the same as the thickness of the flange 6, so that whenthe shoulder 12 formed by the reduced extension 9 rests against theupper face of the flange 6, the lugs 11 are disposed immediately belowthe lower face of the flange 6 and it will be seen that by turning thesleeve, the same will be removably locked to the flange.

The sleeve 8 is adapted to receive an operating shaft 13, the bore ofthe sleeve being of relatively greater diameter than the diameter of theshaft. Formed in the body portion of the sleeve 8 are longitudinallyextending slots 14 which terminate adjacent the shoulder 12, the slots14- extending in tangential relation with the shaft 13. Spring plates 15are adjustably arranged within the slots 11i to project within the boreof the sleeve, the plates being maintained in adjusted position bysetscrews 16 which project through the wall of the sleeve intoengagement with the plates. The plates disposed on one side of thelongitudinal axis of the shaft 13 are arranged at right angles to eachother, and the inner end of each plate 15 is provided on its inner facewith a wearing block 17, the wearing blocks being adapted to engage theperiphery of the shaft 13.

In the practical use of my device, the journal sleeve is mounted in theseparator body as hereinbefore described, with the operating shaft 13thereof projecting through the bore of the sleeve, and the wearing block17 in engagement with the periphery of the shaft at. diametricallyopposite points thereof. Owing to the resiliency of the plates 15, thewear of the shaft 13 will be readily compensated for, and the parallelsprings may be adjusted by moving them outward, so as to allow them tobe sprung wider apart, so that the wearing blocks will engage theperiphery of shafts of greater diameters.

`What I claim is:

1. A device of the character described comprising a sleeve having ashaft rotatably mounted therein, said sleeve having longitudinal slotsformed therein, spring plates endwise adjust-able through said slots anddisposed in tangential relation with the shaft, and means` formaintaining said plates within said slots, as and for the purposedescribed.

2. A device of the character described comprising a sleeve havinglongitudinal slots formed therein, a shaft rotatably mounted in saidsleeve, Springs adjustably arranged in said slots in tangential relationwith the shaft, the inner surfaces of said springs being provided withwearing blocks fixed thereon for engagement with the periphery of saidshaft, and means for maintaining said springs in adjusted postitonwithin said slots, as and for the purpose described.

3; In combina-tion with a body having an inwardly extending flange, theange having an annular bore, of a sleeve having a reduced extension forengagement in the bore of the flange, a shaft rotatably mounted in saidsleeve, said sleeve having longitudinal slots formed therein, inwardlyproj eeting springs arranged in said slots in tangential relationl wit-hthe shaft and wearing blocks formed:

Copies of this patent may be obtained for ve cents each, by addressingthe Commissioner of' Patents,

on the inner ends of said springs for engagement with the periphery ofthe shaft, as and for the purpose described.

el. A device of the character described including a sleeve having' ashaft rotatably mounted therein, said sleeve being provided with slotstherethrough, spring plates directed through said slots and disposed intangential relation with the shaft, each of said plates being of Such alength as to have an end portion thereof extended exteriorly of thesleeve, and retaining means engagea-ble with the plate.

ln testimony whereof I hereunto aiiix my signature in the presenceof twowitnesses.
